# Aosong ASAIR AHT10 & AHT15 # Aosong ASAIR AHT10, AHT15 & AHT20
This is an Arduino library for Aosong ASAIR AHT10, AHT15 Digital Humidity & Temperature Sensor This is an Arduino library for Aosong ASAIR AHT10, AHT15 & AHT20 Digital Humidity & Temperature Sensor
- Supply voltage: 1.8v - 3.6v - Supply voltage: 1.8v - 3.6v
- Temperature range: -40°C..+80°C - Temperature range: -40°C..+80°C

- Relative humidity resolution: 0.024% - Relative humidity resolution: 0.024%
- Relative humidity accuracy: ±2%** - Relative humidity accuracy: ±2%**
- I²C bus speed: 0Hz - 400KHz - I²C bus speed: 0Hz - 400KHz
- Recomended polling frequency: 8sec - 30sec - Recomended polling frequency: 8sec - 30sec***
Supports all sensors features: Supports all sensors features:
- read humidity*** - read humidity****
- read temperature*** - read temperature****
- soft reset - soft reset with sensor initialization
Tested on: Tested on:
- Arduino AVR - Arduino AVR
- Arduino ESP8266 - Arduino ESP8266
- Arduino ESP32
- Arduino STM32 - Arduino STM32
**Prolonged exposure for 60 hours at humidity > 80% can lead to a temporary drift of the signal +3%. Sensor slowly returns to the calibrated state at normal operating conditions.
***If sampling rate of the measurement is too high, the sensor overheats. To prevent the temperature of the sensor from rising > 0.1°C, read sensor once every 2 seconds.
****The library returns 255 if a communication error occurs or if the calibration coefficient is off.
